The reason they do that is to make sure that Ranked matches are on an even playing field. It would be nice if they offered a separate queue for third-person view, like how the different control methods are separated, though that may be spreading things out too much.
The only time I ever played Ranked was for challenges that required it. Otherwise, it takes too long to get into a game, and doesn't really offer anything over the usual Quick Play queue aside from both teams having to use different chumpions from each other. In fact, it offers less, since only one mode is available.
What time do you usually play, GK? It would be fun to team up with you sometime; I've only ever played with an NWR crew one time, would be nice to do more.
